KEY ENVELOPE.

Application ined December 1e, i925. serial No. relanc.

.lt-"is the present practice tor bankingl iustitutions to lease what are termed deposit boxes, to wit, smell drawers provided with locks, which ine/y be opened by keys lur- 5 nich d to the lessees. Despite the usuel preons, possible that such boxes inny ie if .indnlently opened by any employee ot he lessor who hes had access to the keys be- "ore delivery of the seine to the lessee, and thus hed en opportunity making, or heving' mede, e duplicete or duplicates ot the seine.

Therefore, the principal object end etlect ol" our invention is to provide en envelope l5 with ineens so constructed `rind arranged that it may be utilized to seclnde any such originel key, :troni the time of its mainmise ture until its delivery to the lessee.

lt is the usuel practice, ind is desirable, 'to store such l fs in reeks comprising conipzirtnients but slightly larger than the shenks ci two siiniler keys which ere iurnished with erich lock for the use ot the lessee. Therefore, it is e further object isind el'lect ci our invention to provide en envelope which niey be used to seclude such a pair ot keys together end in ysuch manner es not to interfere with the storage 1nd i'einoval oit such key packages with respect to such 30 racks. I

In the forni of ourinvention hereinafter described, such en envelope inclndes e sheet oli ilegible rneterinl which uiey be wrapped :ironnd the shank portions ot the keys which are provided with the bitting` notches i'or the lock tuniblers. Seid sheet is provided with two .narrow desible connecting` members preferably torined in unitary relation there'- with and extending' in elinenient 'from respectively opposite ends thereot. one ot which may be extended through n hole in the handle o'f a key Lund have its end returned parallel with the other connecting; nieinber so that the ends oit said connecting ineinbers may be sealed together, to prevent access to the key except by disruption ot seid seal. Such sea-ling may be etlected by spot weldingor riveting the two connector ends together, :is hereinafter described.

Although such secluding ineens is in no sence burglar proof, it is oi such character :is to rneni'lect il any attempt hns been nitide to open it, and the 'lect that it hes not been tempered with. etici-ds assurance to the les e.: see that no unauthorized p, son hes heil :in

opportunity of marking e duplicate ot' the key or keys thus secluded.

@ur invention includes the various novel tentures construction end erringenient hereinafter incre definitely specified."

F ll is n perspective view of the envelope of Fig'. l, secluding two keys, end in its norinnl sealed condition.

Fig. lll is a longitudinal sectiontil View ot the structure shown in Fig. ll.

Fig. lV is e transverse sectional viewfot seid structure shown in Figs. Il and lll.

Fig. V is e perspective view et ke inoditied forni of envelope, wherein the flexible 'connectors are ij'ornied ot' e. piece or' nietel which wes prininrily seperate 'troni the envelope.

Fig. Vl is e perspective view oit e. ihodilicd form oit envelope,vwherein theilexible conn-ectorsV ere formed of e single piece oit wire. Fig. Vil is n perspective view of the en velope of Fi Vl., secluding two keys end in its normal sealed condition.

Referring' t'o' the torni of Aour invention shown in Figs. l to lV inclusive; the envelope l is conveniently formed oi' `e primarily plane sheet of ductile instal, such es brass or copper; the rectangular body thereot having opposite end edges 2 'end 3 and side edges e and 5. Seid envelope l hns coi'inectors 7 sind S projecting from the rospectively opposite ends of seid body etits edges 2 and 3, in elincinent with said edge 5 end in unitary relation with said body; y

Seid envelope may be bent iipon the toer lines 10, l1, l2, and 13, indicated by dots in Fie'. l, to the tubulnr forni shown in Fig. lV; wherein the edge 5l overlaps the edge 1%. Seid tube is adapted to receive rind seclude the shrinks le of duplicate keys provided with 'the bittings l5, and seid connecter 7 extended through the registered holes 16 in the bow handles l? of seid keys, iindthe end oit said connector returned parallel with seid edge 5 ot the envelope bo'dy but upon the opposite side oit the package so es to present its cud parallel with the end of the connector 8. Seid connectors may then be sceled together by any suitable ineens, l'or instance, by a tubular eyelet i9 extending; through rhein und clinched upon opposite sides thereof.

Seid key shrinks 14: are thus secluded so .by spot welding them at 30. l'Iowever.

that ,neither of them, nor the bittings l5 therco't', can be copied upon another key blank without opening said envelope 1; by breaking either et -said connectors 7 or 8 or disrupting1 said sealing means. Conse duently any attempt to use said keys in any it'raiululent manner above contemplated, is manifested by the damaged condition ot their inclosure, and, it the envelope and seal are intact when delivered to the lessee, the latter is assured that no unauthorized' person has had the opportunity ot making a duplicate of the keys thus secluded. However, said connectors 7 and tl may be easily cut to release said keys tor legitimate use.

The torni of our inifcntion shown in Fig. V differs `lrom that shown in Fig. I, in that the tiexible connectors 2l and 22 are formed ot a single strip ot metal which is primarily separate 'from the envelope body but is connected therewith by extending it under the folded edpgc flap 2xt ot said body. The advantage of such coi'istruction is that .it avoids Waste in cutting; the sheet material which is unavoidable in the production ot envelopes in the form shown in Fig. I, wherein theconnectors 7 and 8 are in unitary relation With the envelope body l. The envelope shoivn in Fig. V may be employed to inclose and seclude a pair of keys in substantially tliesame manner as indicated in Figs. II to IV inclusive.

Fig. VI shows ay modilied lorin of our invention `wherein the Hexible connectors E25 and QG are ormedot a single piece of Wire which is connected with the envelope liody 27 by extending it under the folded edge flap 2S of saidl'io'dy 2T. Ot course. the small cylindrical connectors 25 and 2G are not adapted Vto be connected by the rivet means shown in Figs. II and III. The envelope structure of Fig. VI may bc used to seclude a pair ot keys in substantially thc same manner as shown in Figs. II to IV inclusive and as indicated in Fig. VII, and said connectors Q5 and Qt be seali-dtoocther lor the purpose ot utilizingl the kcy racks atoresaid. any suitable `sealing means may he employed. for the envelopes above conteniplated. provided that it docs not project bcyond the cross sectional diiiu-nsions ot the package, and coiiseiiuently exit-nds within the longitudinally extciiding boundary planes of the package, as shown, for instance, in Figs. II, III and VII.

obvious-that various modifications may be made therein ivithout deiiartingil from the `essential features ot our invention, as defined in the appended claims.

lV'e claim:

l. rlhe combination with an envelope formed of flexible .sheet metal, adapted to be wrapped around a kel and having tivo connector members in integral relation there with, one ot said members being' adapted to extend through a hole in said key and into proximity to the other connector; ol scalini; meansI connecting said connectors, independently ot the body ot said envelope; wherelry a key may be secluded in said envelope until the latter is disrupted or said sealing; means displaced.

The combination with an envelope 'formed of iiexible sheet metal, adapted to he. wrapped around a key and having tivo connector members in integral relation therewith. one oi said members being: adapted to extend through a hole in said key and into proximity to the other connector; ot sealing means, includingl a tubular rivet, connectine` said connectors. independently of the bod)- ot said envelope; whereby a key may he secluded in said envelope until the latter is disrupted or said sealing` means displaced,

3. An envelope termed ol a primarily 'flat sheet ot fiexible material adapted to be Wrapped around the shank oit. a key having' a handle larger than said shank, and having two connector members, in unitary relation therewith`I adapted to extend in priixiinati-z relation at one end ot said key; and scaling; means connecting said connectors; said scaling means and the portions ot `the connectors adjacent thereto being within the longritudinally extending boundary planes ot' the package: whereby tiliepackapge adapted to remo yablyz fit in a rack opening smaller than said handle and snugly fitting the iieriinetci ojt saidy package immediately adjoiiiiuiia said handle, and said key may be secluded iii .said envelope until thc lutter is disrupted or .said

`scalino` means displaci-id.
